Abstract

Despite its excellent properties, polyurea coating waterproofing material is exposed to sunlight when it is applied to the exterior wall of concrete by exposed waterproofing method such as a roof of a building, resulting in a problem of causing a large deterioration in performance compared to initial properties. The purpose of this study is to investigate the effect of carbon fiber incorporation on the performance of carbon fiber - reinforced polyureas and to study the optimum carbon fiber length and content respectively. Result of the study confirmed that the performance of the carbon fiber was improved by 2% or more, and the carbon fiber length was 30 ㎛ and the mixing ratio was 3%. It is expected that stable durability can be secured when manufacturing fiber-incorporated polyureas.
